Geothermal Heat Pumps

GT-PG Geothermal Heat Pump – 50YE


The GT-PG series offers exceptional quality, quiet performance and year round comfort. Optional upgrades include supplemental hot water generation. A single-stage scroll compressor, combined with a single- or (optional) variable-speed motor, corrosion-resistant coil, microprocessor control and quiet operation make this a great choice.

Perhaps best of all is a Federal tax credit still available on qualified geothermal heating and cooling systems. So, you can revel in getting a tax credit of up to 30% of your installed cost of a geothermal system.
